Нами изучалось влияние лазерного излучения красной области спектра на физико-химические показатели (pH и осмос) спермы хряковпроизводителей. Исследования проводились на четырёх группах (контрольная и три опытные) животных различных пород возрастом 18-24 месяца. Установлено, что при воздействии полупроводникового низкоинтенсивного лазера красного цвета длиной волны 620-760 нм и плотностью мощности 3 мВт/см2 продолжительностью 10-30 минут на разбавленную сперму хряков-производителей уровень рН составлял от 7,14 до 7,40 спустя трое суток хранения, что соответствовало норме для использования эякулятов при искусственном осеменении. Показатель осмотического давления повышался в процессе увеличения сроков хранения разбавленных эякулятов и через 72 часа находился в пределах допустимых значений в диапазоне от 314,76 до 316,85 мОсм/л. </p></abstract><trans-abstract xml:lang="en"><p>Exposure of sexual gametes to low-intensity optical radiation is considered to be one of the biosafe methods of increasing the semen fertilizing capacity. We studied the effect of laser irradiation of the red spectrum region on physicochemical parameters (pH and osmosis) of breeding boars’ semen. The studies were conducted on four groups (control and three experimental groups) of animals of different breeds aged 18-24 months. It was found that when diluted semen of breeding boars was exposed to a semiconductor low-intensity red laser with a wavelength of 620-760 nm and a power density of 3 mW/cm2 for 10-30 minutes, the pH level ranged from 7.14 to 7.40 after three days of storage, which corresponded to the norm for the use of ejaculate in artificial insemination. Osmotic pressure increased with increasing storage time of diluted ejaculates and after 72 hours was within acceptable values ranging from 314.76 to 316.85 mOsm/L. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>хряки</kwd><kwd>сперма</kwd><kwd>капацитация</kwd><kwd>биофизическое воздействие</kwd><kwd>лазерное излучение</kwd><kwd>светодиоды</kwd><kwd>обработка</kwd><kwd>pH</kwd><kwd>осмос</kwd><kwd>ионы водорода</kwd><kwd>область спектра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>boars</kwd><kwd>semen</kwd><kwd>capacitation</kwd><kwd>biophysical effects</kwd><kwd>laser irradiation</kwd><kwd>LEDs</kwd><kwd>treatment</kwd><kwd>pH</kwd><kwd>osmosis</kwd><kwd>hydrogen ions</kwd><kwd>spectrum region</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zinc is a master-regulator of sperm function associated with binding, motility, and metabolic modulation during porcine sperm capacitation / M.
